Shelter-in-Place: This Generation's Duck-and-Cover

On the third floor, employees gathering for a staff meeting chose to barricade themselves rather than flee into the hallway where they heard gunshots.

Capt. Mark Vandroff and his colleagues stacked chairs and desks in front of a door and got down on the floor. Two bullets care [sic] through the wall off the conference room, but high above their heads. The [sic] stayed in place for 30 minutes before police evacuated them.

"We were hunkered down, we were on the floor because we had heard the previous gunshot. We heard gunfire and we looked up and there were two bullet holes in the top of the wall of the conference room," Vandroff said.

Rather than make noise by talking, his team texted each other from their smart phones.

By the time it was over, former Navy reservist Aaron Alexis had shot and killed twelve individuals at the Washington Navy Yard in Washington, D.C.

Commander Tim Jirus told Fox News: “For those of us who knew there was an active shooter because they were much closer to where that was happening at, there is shelter-in-place. You lock your door inside your building until someone tells you it’s clear.”

According to the Washington City Paper, “[Metropolitan Police Department] Chief Cathy Lanier said after the first shots were reported this morning, MPD officers were on the scene within two to three minutes, at which point security within Navy Yard had already engaged the shooter. Within seven minutes, Lanier says, an 'active shooter team' was in the building and had 'multiple engagements' with the shooter, the last of which resulted in his death.”
